I used to have this unit in a mogul and it worked fine, I have now fitted it into a 2-4-0 dumpy loco tender and after factory re-set the chuff rate is way to fast. I have messed with the cv's and had it way too slow at a fixed rate but I can't find a happy medium. I am using the lgb reader/programmer and any thoughts on this would be most welcome.

For digital (no sensor, I presume).. CV2 (default '0') if sound starts before loco motion, increase value. CV's 3 and 4 are acceleration and braking respectively (default '3') for without a wheel sensor, and just to confuse, '1' is fast ans '255' is slow. Then we are back to CV64 (default '82') range is 9-255 and you can tweak this for differing wheel diameter, to get 'chuff' about right.
